DRO 100

Multi-axis Display

ACU-RITE DRO 100 Digital Readout 

The ACU-RITE DRO 100 display unit is well suited for general applications on milling, drilling and boring machines and lathes with up to three axes.


The DRO 100 display unit is designed as a sturdy upright unit with splash-proof membrane keypad for use in a workshop. It is equipped with a colour TFT screen for display of position values.


The most important functions are available quickly and directly via function keys. If the DRO 100 is used on a lathe then you can simply switch from radius to diameter display. For lathes with a seperate top slide the sum-display feature on the 3-axis version of the DRO 100 allows you to display the saddle and top-slides either together or seperately.

Data Interfaces

The DRO 100 has a USB port for reading and writing data and files.
